E-commerce & Marketplaces

You take a seller's business details at signup, then send money to the account they typed in. These checks confirm both before the first payout leaves.

Where onboarding breaks

What a seller signup form cannot prove

A signup form collects a trading name, a GSTIN and a bank account number. It cannot tell you whether the business is registered, or whether the account is the seller's.

Marketplaces often answer those two questions with a patchwork of services, and end up with seller identity, business and beneficiary details in different shapes.

Seller intake

Which checks to run on a new seller

Confirm the business with PAN, PAN-to-GST, GST, Udyam or KYB OCR, depending on what the seller gives you. Then confirm the payout leg with Penny Drop, Mobile to Account or VPA services before the first settlement.
